Matthias Koefferlein 6932977273 A few bug fixes and test updates 
- edge pairs are normalized before turning them into polygons.
  This makes flat and deep implementation more consistent.
- deep region and flat regions were not cooperating in geo
  checks
- unnamed layers are not registered in make_layer - this
  does not make sense and will just hold a fake ref
- tests now use GDS to represent texts after transformation
  (with orientation, OASIS can't do this)
- texts are more consistently handled in the tests
- test debug output is not written in the same format
  than golden data unless special normalization is
  requested.
- a non-orientable polygon was converted to orientable in
  a text because this can be represented in GDS consistently
- DRC testsuite uses "polygons" instead of "input" to achieve
  identical behavior for deep and flat mode with respect to
  texts
- dbRegionTests are updated because texts are not allowed
  for non-original layers too

Matthias Koefferlein 30e26c4f96 Avoid an issue with virtual functions 
Reimplementing virtual functions with
"const &" arguments wasn't behaving as
expected because these arguments were
copied.

Now, "const &" for arguments (in virtual
function reimplementation) is not implemented
as a copy.

In addition, now it's possible to declare
results as references always (also if const &).

See gsiTest.cc:1078 for example:

  //  gsi::arg_make_reference makes the function's return value
  //  always being taken as a reference
  gsi::method<C_P, const CopyDetector &, const CopyDetector &, gsi::arg_make_reference> ("pass_cd_cref_as_ref", &C_P::pass_cd_cref)

Matthias Koefferlein aeeb6d7c87 Fixed #200 by introducing layout locking during iteration 
The cause for the problem was that the layout got updated
while iterating causing the mess within the iterator.

This solution is to lock the layout while an iterator
is present. This happens for various Cell and Shapes
iterator, so it's a major enhancement.

Matthias Koefferlein 9c607d7663 Added a first version of the layout to netlist extraction feature 
The main entry point is RBA::LayoutToNetlist which is the
GSI binding for the layout to netlist extractor. For a first
impression about the abilities of this extractor see the
Ruby tests in testdata/ruby/dbLayoutToNetlist.rb.

The framework itself consists of many classes, specifically

- RBA::Netlist for the netlist representation
- RBA::DeviceClass and superclasses (e.g. RBA::DeviceClassResistor and
  RBA::DeviceClassMOS3Transistor) for the description of devices.
- RBA::DeviceExtractor and superclasses (i.e. RBA::DeviceExtractorMOS3Transistor or
  the generic RBA::GenericDeviceExtractor) for the implementation of the
  device extraction.
- RBA::Connectivity for the description of inter- and intra-layer connections.
